In 1957 Bardeen, Cooper, and Schrieffer published their 30-page magnun opus “Theory of Superconductivity.”[1]} This theory introduced a correlated manybody wavefunction based on Fermi surface pairing of electrons demonstrated a year earlier by Cooper. This wavefunction described a thermodynamic condensate of correlated pairs below a critical temperature T\(_c\) , assuming an attractive effective pairing potential arising from exchange of phonons and screened electron-electron scattering. The primary result of their theory was the T\(_c\)  equation (units \(\hbar \) =1, \(k_B=1\) )
\(T_c^{BCS} = 1.14~\Omega ~e^{-1/\lambda ^*}\)
